出现如下错误：
**** ERRORS/WARNINGS IN EQUATION QAfn(sec1)
     274 error(s): vcPower: FUNC DOMAIN: x**c, x < 0 (RETURNED        0)

**** ERRORS/WARNINGS IN EQUATION QAfn(sec2soe)
     5345 error(s): vcPower: FUNC DOMAIN: x**c, x < 0 (RETURNED        0)


前面运行的是这样：
QAfn(sec1)..  QA(sec1) - (0.999997626916371)*QVA(sec1)

      - (0.999997626916372)*QINTA(sec1) =E= 0 ; (LHS = 0)

QAfn(sec2soe)..  QA(sec2soe) - (0.999998061712832)*QVA(sec2soe)

      - (0.999998061712832)*QINTA(sec2soe) =E= 0 ; (LHS = 0)

QAfn(sec2pri)..  QA(sec2pri) - (1.02750274652269)*QVA(sec2pri)

      - (1.02750274652269)*QINTA(sec2pri) =E= 0 ;
     
      (LHS = 2.27373675443232E-13, INFES = 2.27373675443232E-13 ***)



看论坛里有人说是方程左右不平衡，请问怎么才能把方程左右给调平衡了啊，请大神指点（附件是相关程序）
